Have you heard about prototyping? It is an activity for making prototypes of software application. This activity may occur in software development that is comparable to prototyping as from other fields such as manufacturing. And mechanical engineering. Now have you heard about rapid prototyping?

Rapid Prototyping

Rapid prototyping is that the automatic construction of physical objects using solid freeform fabrication. And are used to manufacture models and prototype components. It takes virtual designs (from computer aided design (CAD) or from animation modeling software), transforms them into cross sections, still virtual, and so produce each cross section in physical space. One when subsequent until the model is finished. It’s a WYSIWYG method where the virtual model and the physical model correspond nearly identically.

The machine reads in information from a CAD drawing, and lays down consecutive layers of liquid or powdered material, and in this way create the model from an extended series of cross sections. These layers that correspond to the virtual cross section from the CAD model are pasted along or fused (often using a laser) mechanically to make the ultimate shape. The standard interface between CAD software and fast prototyping machines is the STL file format.


WYSIWYG: an acronym for What You See Is What You Get, utilized in computing to explain a system within which content during editing seems very similar to the ultimate product. It is normally used for word processors, but has different applications, like internet (HTML) authoring.

Now let us see what the use of rapid prototyping is to.
  • Increase effective communication and product lifespan by adding necessary features and eliminating redundant features early within the design .
  • Reduce development timeand expensive mistakes.what is rapid prototyping11
  • Attenuate sustaining engineering changes.

Rapid Prototyping decreases development time by permitting corrections to a product to be created early in the method. By giving engineering, producing, selling, and buying a look at the product early in the design method, mistakes are often corrected and changes can be made while they’re still cheap.

The trends in producing industries continue to emphasize the following:
  • Increasing different variants of products.
  • Increasing product quality.
  • Decreasing product lifespan before obsolescence.
  • Decreasing delivery time.

Rapid Prototyping, also called 3D printing, is an additive manufacturing technology. The method begins with taking a virtual design from modeling or computer aided design (CAD) software. The 3D printer reads the information from the CAD drawing and lays down consecutive layers of liquid, powder, or sheet material-builds up the physical model from a series of cross sections. These layers, that correspond to the virtual cross section from the CAD model, are automatically joined together to form the ultimate form.

Rapid Prototyping uses a typical data interface, implemented because the STL file format, to change from the CAD software to the 3D prototyping machine. The STL file format approximates the shape of a part or assembly using triangular sides. Typically, rapid Prototyping systems will manufacture 3D models within a few hours. Yet, this will vary widely, depending on the kind of machine being employed and also the size and number of models being created.
